Back on Here

Hello all... I am a momma of 3! I have a 7 year old daughter and two sons who are 4 and 2! I just finished a First Responder Class and am going to be taking a FireFighter class. I just recently went in for a physical and they told me I needed to lose at least 15 to 20 pounds. So I am back on here to try this site again! I NEED ideas please on how to lose the baby fat!!! Thanks :)
